Description

  • The invention relates to a drilling device consisting of a drill bit having a drill and a chuck with a chuck body which is releasably, rotatably and axially immovably coupled to the drill spindle, wherein the chuck body on the side facing the drill spindle a pin arranged with non-rotationally symmetrical cross-section and in the drill spindle a pin receptacle are formed with a corresponding to the pin cross section, that the pin has a circumferentially extending groove, and that in the receiving wall a locking member is mounted, which by means of a spindle ring between a protruding into the pin receiving and into the groove position and a retracted from the pin receiving position is adjustable.
  • Drilling devices have long been known in practice, wherein the attachment of the drill chuck to the drill spindle usually takes place via a threaded connection, for which an external thread is formed on the drill spindle, with which the drill spindle can be screwed into a spindle receptacle of the drill chuck with an internal thread , This threaded connection is detachable and represents an axially non-displaceable coupling of the drill chuck to the drill spindle; this connection is non-rotatable in the sense that the drill chuck is screwed onto the drill spindle with a high torque, which is greater than the torques to be transmitted by the drill spindle to the drill chuck. A further additional security is known for which a screw is made through the passage connecting the spindle receptacle to the tool receptacle of the chuck body and screwed into the front end of the drill spindle.
  • As a result, although the drill chuck is releasably connected to the drill spindle, but it requires a relatively high effort to exchange a drill chuck in the drilling device for another.
  • In the DE 40 37 791 C1 already a drilling device is shown in the drill chuck a pin is provided for connection to the machine spindle. This pin has a Flachkant at its end, which engages in use with a corresponding Flachkantabschnitt in the machine spindle and thus the drill chuck rotatably secured relative to the machine spindle. Furthermore, an annular groove or groove is provided on the pin, can engage in the detent balls. The axially adjustable sleeve holds the locking balls in the locking position, because it is acted upon by a conical coil spring. To solve the latching a arranged on the chuck key must be operated, which shifts the sleeve axially in the direction of the drill against the force of the coil spring and thus releases the locking of the pin. However, it is disadvantageous in this drilling device, on the one hand, the button must be pressed and on the other hand must be pulled on the chuck to release the connection between the chuck and the drill.
  • The invention is therefore based on the object, a drilling device of the type mentioned in such a way that the connection between the chuck and the drill is additionally secured and provides improved concentricity properties of the drilling device.
  • This object is achieved according to the invention in a drilling device of the type mentioned above in that on the drill spindle ( 4 ) a circular, coaxial with the spindle axis ( 28 ) lying mating surface ( 29 ) and on the chuck ( 3 ) a circular, coaxial to the feed axis ( 6 ), for cooperation with the mating surface ( 29 ) provided centering surface ( 30 ) are formed, and the mating surface ( 29 ) on the outer circumference of the drill spindle ( 4 ) and on the chuck body ( 5 ) a collar ( 31 ) with the formed on the inner peripheral surface centering surface ( 30 ) are arranged.
  • The drill chuck of the drilling device is the coupling link between the drill and the tool to be driven in rotation. In this drilling device, there is the advantage that the tensioned in the chuck tool does not have to be stretched to a change of the tool from the drill chuck, but can be separated together with the drill chuck from the drill. This is an advantage, in particular, when switching between tools with a large difference in the shank diameter, since in this case the clamping jaws associated with the chuck must be adjusted almost over their entire adjustment range. In this case, it is easier to replace the tool together with the chuck, wherein the easy changeability of the drill chuck expands the field of application of the drilling device, since drill chucks with different clamping ranges can be kept ready. In addition, there is the advantage that directly in the drill spindle without the interposition of the drill chuck, a tool whose shaft is formed corresponding to the pin of the drill chuck, can be maintained. In the drilling device, the non-rotationally symmetrical cross-sectional shape of the pin and the pin-shaped shank-receiving principle of the torque transmission, while the axial securing of the chuck to the drill spindle via the interaction of the locking member is done with the groove.
  • Due to the non-rotationally symmetrical cross-sectional shape of the pin and the pin receiving it is difficult to achieve a precise mutual alignment of drill chuck and drill spindle, so that the concentricity properties can be affected. In order to avoid such an impairment, it is further provided that on the spindle a circular, coaxial with the spindle axis mating surface and on the chuck a circular, coaxial with the chuck axis, provided for cooperation with the mating surface centering surface is formed. The centering surface and the mating surface cause a precise and easily reducible alignment of the chuck and the drill spindle relative to each other. This alignment can be achieved in a particularly simple manner without further measures when plugging the chuck with the pin in the pin receiving the drill spindle in that in the pin receiving on the receiving wall, the mating surface is formed to cooperate with the pin associated centering. A centering in the spatial proximity of the center of gravity of the chuck body can be achieved by the centering surface is arranged at the base of the pin and the mating surface at the mouth of the pin receiving. As an alternative to such internal centering is also possible to effect an external centering by the mating surface is formed on the outer circumference of the drill spindle and the chuck body an annular collar with the formed on the inner peripheral surface centering.
  • For correct alignment of the drill chuck and the drill spindle in the axial direction of the drill spindle and the chuck body for mutual contact certain plan surfaces are formed, expediently on the front side of the pin and the bottom of the pin receiving the radially extending planar surfaces are formed. Alternatively, there is also the possibility that the radially extending plane surfaces are formed on the front side of the drill spindle and at the base of the pin, so assigned to the use of the largest possible axial guide length, the radial plane surfaces either the one or the other end of the pin or the pin receiving are.
  • Conveniently, the pin is designed as a polygon, preferably as a hexagon, since due to the widespread use of such designed tools this can also be coupled directly to the drill spindle instead of the drill chuck.
  • For a safe and uniform force transmission, the locking member is provided several times. The spindle ring has a pocket with inclined pocket walls for the locking member, so that is secured in the removal of the locking member from the pin receiving this in a provision for the re-introduction of the pin.
  • A preferred embodiment is characterized in that the spindle ring is designed as a sleeve in which a securing spring is arranged between a sleeve shoulder and a spindle shoulder, which acts on the sleeve in a direction leading away from the catch member. By cooperating with the locking spring sleeve ensures that the locking member is displaced during use of the drilling device in the pin receiving, while for the change of the drill chuck in a simple manner, the sleeve must be adjusted only in the axial direction against the force of the spring, that the locking member can enter the pocket. According to a further alternative embodiment, it is provided that the chuck for adjusting the running in inclined to the chuck axis guide mounts guided jaws has a relative to the chuck body rotatable control sleeve on which a voltage applied to the sleeve by the force of a spring sleeve is mounted. This embodiment has the advantage that for adjusting the sleeve and thus for separating the chuck from the drill spindle not directly the sleeve must be taken and adjusted, since this adjustment can also be effected indirectly by the grip sleeve.
  • In order to facilitate the separation of the drill chuck from the drill spindle, an ejector which is acted upon by the force of a spring and which comes into contact with the pin inserted into the pin receptacle is arranged in the pin receptacle.
  • The axial securing of the ejector in the pin receiving can be effected in a simple manner, that in the receiving wall, a securing the axial position of the ejector securing member is adjustably mounted. At the ejector extending in the circumferential direction Auswerferkehlung and the spindle ring a locking member pocket is formed and placed so that at the same time the locking member can enter into the pocket and the securing member in the securing member pocket.
  • A particularly preferred embodiment of the invention is characterized in that the drill spindle is formed in two parts with a threaded machine spindle and a spindle adapter, in which one end a threaded receptacle and the other end is formed the pin receiving. In this embodiment, it is also possible to convert drills as part of the drilling device in which for coupling with conventional chucks only a thread is formed at the spindle end, which is used to fix the spindle adapter instead of a conventional chuck, which is responsible for the According to the invention drilling device has required properties.
